FRAUD DETECTION VIA INCREMENTAL FRAUD MODELING

Abstract:

An approach is disclosed for identifying fraudulent transactions. The approach receives transaction order data for a transaction order. The approach applies a fraud model to the received transaction order data and generates an initial score. The approach determines whether to tentatively accept the received transaction order based on the generated initial score being less than a first threshold value. The approach applies, in response to tentatively accepting the received transaction order, an incremental fraud model to the received transaction order data and generates a second score. The approach denies the received transaction order when the second score is greater than a second threshold value.
